youth or youths

"If we're going to watch a movie on the laptop, this one's on their phone, this one's eating, this one's listening to music or watching a video," Gallo said. "There's always so much going on. I get sensory overload. I've just got to step out of the room for a second. It's too much."

This sentiment isn't unique to members of her generation, the tribe of 13- to 21-year-olds known as Generation Z. Many of today's youth are finding that technology has grown to dominate their free time.

Shouldn't it be "youths" instead?

Thanks.
